T0 all whom t 11m/y' concern,.- l

Be it known that l, DANIEL GREEN SAUN- DERS, Jr., a citizen of theUnited States, and a resident of Kansas City, Missouri, have inventedcertain new and useful Improvements.

in Sash-Fasteners, of which the following is a specification containinga full, clear, and exact description, reference being had to theaccompanying drawings, forming a part thereof.

My invention 'relates to sash-fasteners and the object of my inventionis to construct a simple inexpensive sash -fastener that will readilypermit either one or both of the sash of a window to be opened a shortdistance for the purposes of ventilation and which will at the same timevery effectively lock the sash together and prevent their being openedto a sufficient degree to permit the entrance of an intruder.

My invention, consists in a ratchet-plate which is secured to the siderail of the upper sash and a pair of springactuated pins carried in ahousing that is fixed. to the top of the rail of the lower sash andwhich pins engage the plate by the upper sash.

My invention further consists in certain novel features of constructionand arrangement of parts that will be hereinafter more fully shown,specified, and claimed.

In the drawings, Figure 1 is a perspective view of the meeting cornersof a pair of sash, the same being equipped with my improved fastener.Fig. 2 is a vertical section taken approximately on the line 2 2 of Fig.l. Fig. 3 is a horizontal section taken approximately on the line 3 3 ofFig. 2.

Referring by numerals to the accompanying drawings, 1 indicates the siderail of the upper sash; 2, the lower meeting-rail thereof; 3, the siderail of the lower sash; and 4 the top meeting-rail thereof.

The ratchetplate of the fastener is preferably constructed of a heavypiece of sheet metal, although it may be cast, if desired, and comprisesa plate 5 ,the right-hand end of which is bent outwardly at right anglesto the body portion, as indicated by 6, and then laterally parallel withthe body portion 5, as indicated by 7, thus forming a groove 8 beneaththe right-hand edge of said plate. This plate is positioned on the faceofthe lower end of the right-hand side rail 1 of the upper sash and issecured thereto by means of screws 9 or in any other suitable manner.

A series of downwardly-projecting teeth 'to form these teeth.

1() is formed on the face of the plate 5 by cutting a pair of verticalslits through said plate and then cutting a slit transversely betweenthe lower ends of said vertical slits and bending the material betweensaid slits outwardly The outer ends of these teeth occupy the same planeas that occupied by the laterallybent edge 7, previously described. Theupper end of plate 5 is bent forwardly, as indicated by 11 and thenceupwardly and rearwardly, as indicated by 12, the extreme upper endresting directly against the edge of the rail 1, thus forming awedge-shaped upper end for the plate 5. A notch or opening 13 is formedin the bent portions 6 and 7 of the plate at a point between the twolowermost teeth 10, the purpose of which opening will be hereinaftershown.

14 indicates a rectangular metallic housing that is located on top ofthe right-hand end of the top meeting-rail 4 of the lower sash, andarranged transversely within this housing is a partition 15, having apair of apertures 16 therein, and formed in the front wall of thishousing 14 in alineinent with these apertures 16 is a pair of apertures17. Arranged for horizontal movement through the left-hand pair ofalined apertures 16 and 17 is a pin 18, the forward end of which isintended to engage beneath the teeth 10 of the plate 5. A small pin 19is vertically arranged in the body of this pin 18 and projects upwardlythrough the horizontally-arranged slot 20, formed in the top of thehousing 14,

the ends of which slot are extended slightly at right angles toward theleft-hand side of said housing, as indicated by 21. Arranged to slidethrough the right-hand pair of alined apertures 16 'and 17 is a pin 22,the forward end of which travels along the edge of the portion 7 of theplate 5, and a lug 23 is formed integral with the forward end of saidpin 22, which lug normally travels in the groove or space 8 beneath theportion 7. Seated in this pin 22 is a vertical guide-pin 24, thattravels through the slot 25, formed in the top of the housing 14.Located upon the pin 26 in the rear end of the housing 14 is acoilspring 27, the ends of which are extended outwardly away from oneanother, and the rear ends of the pins 18 and 22 bear directly againstthe ends of this spring.

ln the use of my improved sash-fastener and when it is desired to openeither one of the sash for the purpose of ventilation the pin 18 ismoved rearwardly by engaging the IOO IIO

small pin 19, that projects through the slot 20, so that the point ofsaid pin 18 is free from the teeth 10. Then the lower sash is elevatedor the upper sash is lowered to the desired point, and as the pin 18 isallowed to move outwardly to its limited movement b`y the action of thecoil-spring 27 the forward end thereof will engage beneath one of theteeth 10, and thus hold the sash locked. The lug 23 on the end of thepin 22 during this movement moves upwardly or downwardly behind thelaterally-bent edge 7. The lug being so positioned prevents the sashfrom being separated even to the slightest degree. I/Vhen it is desiredto move either one or both of the sash upwardly or downwardly to theirlimit of movement, which is of course much greater than the limit ofmovement allowed by the sash-fastener, the pin 18 is moved rearwardly bymeans of the pin 19, and the pin 18 is slightly rocked, and said pin 19is engaged in the rear one of the laterally-eX- tended ends of the slot20, This action holds the pin 18 locked against forward movement. Whenthe lower sash is elevated so that the pin 22 is in alinement with thenotched or cut-away portion 13, said pin 22 is moved rearwardly byengaging the pin 241, and thus the lug 23 passes out of the groove orspace 8 through the notched or cut-away portion 13, and as both of thelocked pins are now disengaged from the plate 5 each sash may be movedupwardly or downwardly to its limit of movement.

A sash-fastener of my improved construction is very simple, inexpensive,may be readily applied to sash already in a windowframe, and saidsash-fastener even when locked allows the sash to shift laterally aslight distance in either direction during their movement up and down,and said fastener forms a very effective lock for the two sash when thesame are opened slightly to allow ventilation.

I claim- 1. In a sash-fastener, the combination with a toothed platesecured to the upper sash, and having one edge upwardly turned andoutwardly bent, of a housing secured to the opposite sash, aspring-actuated pin for engaging the teeth of the first-mentioned plate,a second spring-actuated pin arranged in the housing, and a lug integralwith the forward end of said last-mentioned pin for" engaging beneaththe upwardly-turned outwardly-bent edge ofthe toothed plate;substantially as specified.

2. In a sash-fastener, the combination with a toothed plate fixed to oneof the sash and having an upwardly-bent and outwardlyturned edge, of ahousing secured to the opposite sash, a pair of spring-actuated pinsarranged in said housing, one of which pins engages beneath the teeth ofthe plate, a lug integral with the point of the opposite pin forengagement beneath the upwardly-bent and outwardly-turned edge, andoperatingpins seated in the spring-actuated pins and passing upwardlythrough slots formed in the top of the housing for withdrawing theispring-actuated pins; substantially as specied.

In testimony whereof I have signed my name to this specification inpresence of two subscribing witnesses.
